BACKGROUND

Technical Field

This disclosure relates generally to camera module components, and, morespecifically, to the use of multiple cameras for zoom functions inmobile devices.

Description of the Related Art

The advent of small, mobile multipurpose devices such as smartphones andtablet or pad devices has resulted in a need for high-resolution, smallform factor cameras, capable of generating high levels of image quality,for integration in the devices.

Increasingly, as users rely on multifunction devices as their primarycameras for day-to-day use, users demand features, such as zoomphotography, that they have become accustomed to using indedicated-purpose camera bodies. The zoom function is useful forcapturing the details of a scene or alternatively capturing the contextin which those details exist. The ability to change focal length toachieve zoom effects is sufficiently compelling to users of dedicatedpurpose cameras that it compels them to carry bags with an array ofremovable lenses, each of which weighs more and takes up more space thanmany common examples of a multifunction device, such as a phone.

Providing the zoom feature in a camera unit of a multifunction devicehas traditionally required moving mechanical parts that increasecomplexity and cost of the device. Such moving parts also reducereliability of the device and take up valuable space inside the device,which puts the desire for zoom functions in direct conflict with thedesire for smaller camera units that take up less space in themultifunction device.

“Configured To.” Various units, circuits, or other components may bedescribed or claimed as “configured to” perform a task or tasks. In suchcontexts, “configured to” is used to connote structure by indicatingthat the units/circuits/components include structure (e.g., circuitry)that performs those task or tasks during operation. As such, theunit/circuit/component can be said to be configured to perform the taskeven when the specified unit/circuit/component is not currentlyoperational (e.g., is not on). The units/circuits/components used withthe “configured to” language include hardware—for example, circuits,memory storing program instructions executable to implement theoperation, etc. Reciting that a unit/circuit/component is “configuredto” perform one or more tasks is expressly intended not to invoke 35U.S.C. § 112, sixth paragraph, for that unit/circuit/component.Additionally, “configured to” can include generic structure (e.g.,generic circuitry) that is manipulated by software and/or firmware(e.g., an FPGA or a general-purpose processor executing software) tooperate in manner that is capable of performing the task(s) at issue.“Configure to” may also include adapting a manufacturing process (e.g.,a semiconductor fabrication facility) to fabricate devices (e.g.,integrated circuits) that are adapted to implement or perform one ormore tasks.

“First,” “Second,” etc. As used herein, these terms are used as labelsfor nouns that they precede, and do not imply any type of ordering(e.g., spatial, temporal, logical, etc.).

“Based On.” As used herein, this term is used to describe one or morefactors that affect a determination. This term does not forecloseadditional factors that may affect a determination. That is, adetermination may be solely based on those factors or based, at least inpart, on those factors.

In some embodiments, the camera system includes a processing unitconfigured to assign to the first image of a first visual field 1086 andthe second image a time indexing feature for establishing that the firstimage and the second image of a first visual field 1088 weresimultaneously captured. In some embodiments, the first camera unit 1082includes a lens having a folded lens configuration (not shown) with alonger focal length 1090 than a focal length 1092 of a lens of thesecond camera unit 1084, and the first visual field 1088 is centered ona second visual axis aligned with a first visual axis on which the firstvisual field 1086 is centered. In some embodiments, the first cameraunit 1082 includes a first moveable lens (shown below with respect toFIG. 1C) and a first image sensor attached a chassis of the camera unit,the second camera unit includes a lens and a second image sensormoveably attached a chassis of the second camera unit 1084.

In some embodiments, the first camera unit 1082 includes a firstmoveable lens and a first image sensor attached a chassis of the first1082 camera unit, and the second camera unit 1084 includes a lens (shownbelow with respect to FIG. 1C) and a second image sensor moveablyattached a chassis of the second camera unit. In some embodiments, thefirst camera unit 1082 and the second camera unit 1084 include a firstimage processing pipeline and a second image processing pipeline,respectively.

In some embodiments, the first image and second image are of differentmedia types. For example, in some embodiments, the first image is amoving image data structure captured at a first frame rate. In someembodiments, the second image is a moving image data structure capturedat a second frame rate. In some embodiments, the second frame rate isfaster than the first frame rate. In some embodiments, the first imageis a still image taken at time t(0), and the second image is a movingimage data structure captured over a time interval including t(0).

In some embodiments, the first image has a first resolution and thesecond image has a second resolution. An example of the use of a firstimage that is a moving image data structure at a first frame rate and asecond image that is a moving image data structure at a second framerate arises in that some embodiments include second camera module 1084recording 720 p (also known as 720 pixels of vertical resolutionprogressive scan) slow motion video at 240 frames per second while firstcamera module 1082 is capturing 4K (horizontal resolution on the orderof 4,000 pixels) video at 30 frames per second. In some embodiments, theanalog-to-digital converter bandwidth required for each separate moduleto achieve the recording is 220-270 Mpixels/s. Achieving the samefunctionality with conventional single camera module technology requiresup to 32 times higher analog-to-digital converter bandwidth for a singlecamera module if it is compared to embodiments in which there is a 2×difference in focal length from wide to tele module, providing benefitsin terms of power, thermal dissipation, storage bandwidth, storagecapacity, and actual achievable frame rates combined with zoomcapability.

A use case for some embodiments is well-illustrated with respect tosports photography. In one example use case, it is possible to imagine auser of portable multifunction device 1080 filming a batter in abaseball game. Recording video of the game with portable multifunctiondevice 1080 from bleachers, not shown, a user may decide to zoom in tocapture a batter swinging and hitting the ball in slow motion usingsecond camera module 1084 recording 720 p slow motion video at 240frames per second, but may subsequently want to switch to thesimultaneously captured 4K video from first camera module 1082 at 30frames per second of resulting home run in high quality video of thefull baseball field, to capture the moments where the opposing teamscrambles to catch the ball and the batter is running from base to base.Some embodiments enable this mixed-video capture by simultaneouslyrecording using second camera module 1084 as a telephoto camera modulein a 240 frames per second slow motion mode while at the same time usingfirst camera module 1082 as a wide camera module in a 4K at 30 framesper second. After capturing a data structure including both videostreams the awesome moment, some embodiments provide for a mixed-videodata structure and an interface for the video streams from the twoseparate camera modules to be manually or automatically edited andcombined to create a more engaging media which may contain normal 1080pvideo, 4K high resolution video, 720 p motion video, and still images.In the example described above, this mixed-video media both captures theclose up expressions of players, the peak action in slow motion, andframes it all in the context of a great play in a baseball game.

Another example of a use case for some embodiments arises in the contextof capturing a child extinguishing candles on a birthday cake. In suchan example, one can imagine a child about to blow out the candles on thebirthday cake while all her friends are singing a birthday song. In someembodiments, second camera module 1084 can be used as a telephoto cameramodule to zoom in on the face of the child as she is about to blow outthe candles and first camera module 1082 can capture a burst of highresolution still images of her smiling face. In some embodiments, firstcamera module 1082 is simultaneously capturing standard 1080p 30 framesper second video of the entire group of kids gathered and singing aroundthe cake. Some embodiments provide an editing interface for combiningthe video stream from the wide camera module, either manually orautomatically, with the close up portraits to create a much moreengaging media experience which can be shared. As the two camera modulesare synchronized in time, the still images can easily be automaticallyinserted at the right time in a final video stream.

FIG. 1B illustrates a user interface for a multiple camera system forportable zoom, according to at least some embodiments. A portablemultifunction device 100 displays a first image of a first visual field104 captured by a first camera unit and a second image of a secondvisual field 102 simultaneously captured by a second camera unit of themultifunction device 100. A zoom control 106 is displayed within firstimage of a first visual field 104. In the embodiment shown, zoom control106 is an area of first image of first visual field 104, that, inresponse to control actuation through the touch screen of portablemultifunction device 100, is used as a control for toggling the displaymode for displaying first image of a first visual field 104 captured bya first camera unit and second image of a second visual field 102simultaneously captured by a second camera unit of the multifunctiondevice 100.

Some embodiments assign metadata to the first image 104 and the secondimage 102 for a time indexing feature for establishing that the firstimage 104 and the second image 102 correspond as having beensimultaneously captured. Some embodiments display the first image 104 ina screen interface with a control (e.g., similar to control 106) forswitching to display of the second image 102, and, responsive to anactuation of the control 106, display the second image 102 in place ofthe first image 104. Some embodiments generate a synthetic intermediateimage at least in part from data of the first image 104 and data of thesecond image 102.

FIG. 1C depicts a side view of an example embodiment of camera module,according to at least some embodiments. Camera module 1000, which is anembodiment of cameras 1564 a-b discussed below, includes cameracomponents such as an optics module (e.g., a lens barrel) 1002 attachedto an optics holder 1003 and a magnet holder 1006. An image sensor 1070,which may or may not be mounted on a substrate that is not shownseparately in FIG. 1C, is attached to a camera module base 1008. Thecamera components may further include, in addition to components such aspower and remote control connections not shown, a cover 1012 andsuspension wires 1020.

Optics module 1002 may be suspended on the base assembly 1008 bysuspension of the upper springs 1030 and the suspension wires 1020.Camera components may include one or more of, but are not limited to,optics 1002, optics holder 1003, magnet holder(s) 1006, upper spring(s)1030, and lower spring(s) 1032. The upper and lower spring(s) may becollectively referred to herein as optics springs. An optics module(e.g., a lens or lens assembly or lens barrel) 1002 may be screwed,mounted or otherwise held in or by an optics holder 1003. In at leastsome embodiments, the optics 1002/optics holder 1003 assembly may besuspended from or attached to the magnet holder 1006 by upper spring(s)1030, and lower spring(s) 1032. Note that upper spring(s) 1030 and lowerspring(s) 1032 are flexible to allow the optics assembly 1000 a range ofmotion along the Z (optical) axis for optical focusing, wires 1020 areflexible to allow a range of motion on the XY plane orthogonal to theoptical axis for optical image stabilization.

Note that, in some embodiments, a camera may not include magnets andmagnet holder(s) 1006, but may include a yoke or other structure 1006that may be used to help support the optics assembly on suspension wires1020 via upper springs 1030. In general, other embodiments of an opticsassembly 1000 may include fewer or more components than the exampleoptics assembly 1000 shown in FIG. 1C. Also note that, while embodimentsshow the optics assembly 1000 suspended on wires 1020, other mechanismsmay be used to suspend an optics assembly 1000 in other embodiments.

The autofocus yoke (e.g., magnet holder(s) 1006) acts as the supportchassis structure for the autofocus mechanism of actuator 1000. The lenscarrier (optics holder 1003) is suspended on the autofocus yoke by anupper autofocus (AF) spring 1030 and a lower optics spring 1032. In thisway when an electric current is applied to the autofocus coil, Lorentzforces are developed due to the presence of the four magnets, and aforce substantially parallel to the optical axis is generated to movethe lens carrier, and hence lens, along the optical axis, relative tothe support structure of the autofocus mechanism of the actuator, so asto focus the lens. In addition to suspending the lens carrier andsubstantially eliminating parasitic motions, the upper spring 1030 andlower spring 1032 also resist the Lorentz forces, and hence convert theforces to a displacement of the lens. This basic architecture shown inFIG. 1C is typical of some embodiments, in which optical imagestabilization function includes moving the entire autofocus mechanism ofthe actuator (supported by the autofocus yoke) in linear directionsorthogonal to the optical axis, in response to user handshake, asdetected by some means, such a two or three axis gyroscope, which sensesangular velocity. The handshake of interest is the changing angular tiltof the camera in ‘pitch and yaw directions’, which can be compensated bysaid linear movements of the lens relative to the image sensor.

In at least some embodiments, the suspension of the autofocus mechanismon the actuator 1000 support structure may be achieved by the use offour corner wires 1020, for example wires with a circular cross-section.Each wire 1020 acts as a flexure beams capable of bending withrelatively low stiffness, thus allowing motion in both optical imagestabilization degrees-of-freedom. However, wire 1020 is in someembodiments relatively stiff in directions parallel to the optical axis,as this would require the wire to stretch or buckle, thus substantiallypreventing parasitic motions in these directions. In addition, thepresence of four such wires, appropriately separated allows them to bestiff in the parasitic tilt directions of pitch and yaw, thussubstantially preventing relative dynamic tilt between the lens andimage sensor. This may be seen by appreciating that each wire 1020 isstiff in directions that require it to change in length, and hence thefixed points at the ends of each wire (eight points in total) willsubstantially form the vertices of a parallelepiped for all operationalpositions of the optical image stabilization mechanism.

In some embodiments, no magnetsare disposed proximate a fourth side of the second camera unit 1204 a.The fourth side of the second camera unit 1204 a may be opposite thefirst side of the second camera unit 1204 a.

In some examples, the first camera unit 1202 a may be smaller in one ormore dimensions than the second camera unit 1204 a. For example, thecorner magnet and coil arrangement of the first VCM actuator may allowfor a smaller X, Y, and/or Z dimension of the first camera unit 1202 athan a corresponding X, Y, and/or Z dimension of the second camera unit1204 a. For instance, the broken line illustrated in FIG. 12A includes atapered portion 1240 a that indicates a difference in size between thefirst camera unit 1202 a and the second camera unit 1204 a.

In some embodiments, the first camera unit 1202 a may be configured tocapture a first image of a first visual field.

In some examples, the first camera unit 1202 a and the secondcamera unit 1204 a may be configured to simultaneously capture the firstimage of the first visual field and the second image of the secondvisual field, respectively. The second visual field may be a subset ofthe first visual field. Furthermore, in some embodiments, the firstoptical package of the first camera unit 1202 a may be configured for afirst focal length, and the second optical package of the second cameraunit 1204 a may be configured for a second focal length. The secondfocal length may be a different length than the first focal length. Insome examples, the first optical package of the first camera unit 1202 amay be configured with a wide-angle lens and the second optical packageof the second camera unit 1204 a may be configured with a telephotolens.

In some embodiments, the first camera unit 1202 a and the second cameraunit 1204 a may include any suitable component, arrangement,architecture, and/or functionality disclosed herein. In somenon-limiting examples, the first VCM actuator and/or the first cameraunit 1202 a may be configured, and/or function, similar to one or moreof the camera modules that include a symmetric magnet arrangement (e.g.,a corner magnet arrangement) discussed above, e.g., with reference toFIG. 3. In some non-limiting examples, the second VCM actuator and/orthe second camera unit 1204 a may be configured, and/or function,similar to one or more of the camera modules that include an asymmetricmagnet arrangement discussed above, e.g., with reference to FIGS.10A-10B. Additionally or alternatively, the first camera unit 1202 aand/or the second camera unit 1204 a may include an architecture similarto one or more of the architectures discussed above, e.g., withreference to FIG. 1C.

In some embodiments, the autofocus coil 1222 a of the first VCM actuatormay be attached to the first optical package of the first camera unit1202 a. A yoke component (not shown) of the first camera unit 1202 a maysupport and house the four magnets 1206 a-1212 a of the first VCMactuator. Each of the magnets 1206 a-1212 a may be poled so as togenerate a magnetic field, the useful component of which for theautofocus function is orthogonal to the first optical axis. The magneticfield for all four magnets may all either be directed towards theautofocus coil 1222 a, or away from the autofocus coil 1222 a, so thatthe Lorentz forces from all four magnets act in the same direction alongthe first optical axis, thereby causing the autofocus coil 1222 a andthe first optical package to move along the first optical axis. The yokecomponent may act as a support chassis structure for the autofocusmechanism of the first VCM actuator. The first optical package may besuspended on the yoke component by an upper spring (e.g., the upperspring 1030 illustrated in FIG. 1C) and a lower spring (e.g., the lowerspring 1032 illustrated in FIG. 1C). In this way when an electriccurrent is applied to autofocus coil 1222 a, Lorentz forces aredeveloped due to the presence of the four magnets 1206 a-1220 a, and aforce substantially parallel to the first optical axis is generated tomove the first optical package, and hence one or more lens elementswithin the first optical package, along the first optical package,relative to the yoke component so as to focus the lens. In addition tosuspending the first optical package and substantially eliminatingparasitic motions, the upper spring and lower spring may also resist theLorentz forces, and hence convert the forces to a displacement of thelens.

In some embodiments, the suspension of the yoke component may beachieved by the use of four corner wires (e.g., the suspension wires1020 illustrated in FIG. 1C), for instance, wires with a circularcross-section. Each wire may act as a flexure beam capable of bendingwith relatively low stiffness, thus allowing motion in both opticalimage stabilization degrees-of-freedom. In some embodiments, the wiresmay be relatively stiff in directions parallel to the optical axis, asthis would require the wire to stretch or buckle, thus substantiallypreventing parasitic motions in these directions. Furthermore, thepresence of four such wires, appropriately separated allows them to bestiff in the parasitic tilt directions of pitch and yaw, thussubstantially preventing relative dynamic tilt between the lens andimage sensor.

Embodiments may achieve two independent degree-of-freedom motion,orthogonal to the first optical axis, by using the optical imagestabilization coils 1214 a-1220 a. In some cases, a first pair of theoptical image stabilization coils 1214 a-1220 a may act together todeliver controlled motion in one linear axis orthogonal to the firstoptical axis, and a second pair may deliver controlled motion in adirection substantially orthogonal to the first pair. The optical imagestabilization coils 1214 a-1220 a may be fixed to a base component(e.g., the base 1008 illustrated in FIG. 1C) of the first camera unit1202 a, and when current is appropriately applied, the optical imagestabilization coils 1214 a-1220 a may interact with the magnets 1206a-1212 a to generate Lorentz forces that move the first optical packageas desired along one or more directions orthogonal to the first opticalaxis.

In various embodiments, the first camera unit 1202 a may include animage sensor (e.g., the image sensor 1070 illustrated in FIG. 1C). Theimage sensor may be disposed below the first optical package such thatlight rays may pass through one or more lens elements of the firstoptical package (e.g., via an aperture at the top of the first opticalpackage) and to the image sensor.

In some embodiments, the autofocus coils 1236 a-1238 a of the second VCMactuator may be attached to opposing sides, or opposing portions, of thesecond optical package of the second camera unit 1204 a. A yokecomponent (not shown) of the first camera unit 1202 a may support andhouse the magnets 1224 a-1228 a of the second VCM actuator. In someexamples, the second magnet 1226 a and the third magnet 1228 a may eachbe dual pole magnets that interact with the autofocus coils 1236 a-1238a. Each of the dual pole magnets may include opposing polarities, asdiscussed above with reference to FIGS. 10A-11B and as discussed belowwith reference to FIG. 12C. The second magnet 1226 a may be a dual polemagnet that interacts with the first autofocus coil 1236 a, and thethird magnet 1228 a may be a dual pole magnet that interacts with thesecond autofocus coil 1238 a. The interaction between the dual polemagnets 1226 a-1228 a and the autofocus coils 1236 a-1238 a may generateforces that move the optical package along the second optical axis foroptical focusing.

The second VCM actuator may include four suspension wires (e.g., thewires 1020 a illustrated in FIG. 1C). The second optical package may besuspended with respect to a base structure (e.g., the base 1008illustrated in FIG. 1C) by suspending one or more upper springs (e.g.,the upper springs 1030 illustrated in FIG. 1C) on the suspension wires.In some embodiments, the second VCM actuator may include one or morelower springs (e.g., the lower springs 1032 illustrated in FIG. 1C). Theupper spring(s) and the lower spring(s) may be flexible to allow thesecond optical package a range of motion along the second optical axisfor optical focusing, and the suspension wires may be flexible to allowa range of motion on one or more directions orthogonal to the opticalaxis for optical image stabilization.

Embodiments may achieve two independent degree-of-freedom motion,orthogonal to the second optical axis, by using the optical imagestabilization coils 1230 a-1234 a. The optical image stabilization coils1230 a-1234 a may be fixed to a base component (e.g., the base 1008illustrated in FIG. 1C) of the second camera unit 1204 a, and whencurrent is appropriately applied, the optical image stabilization coils1214 a-1220 a may interact with the magnets 1206 a-1212 a to generateLorentz forces that move the first optical package as desired along oneor more directions orthogonal to the first optical axis. In some cases,a first pair of optical image stabilization coils 1232 a-1234 a mayinteract with the pair of dual pole magnets 1226 a-1228 a to delivercontrolled motion in a first direction orthogonal to the second opticalaxis. The first optical image stabilization coil 1230 a may interactwith the first magnet 1224 a, which may be a single pole magnet, todeliver controlled motion in a second direction orthogonal to the secondoptical axis and the first direction.

In various embodiments, the second camera unit 1204 a may include animage sensor (e.g., the image sensor 1070 illustrated in FIG. 1C).

FIG. 12C depicts an example embodiment of a camera system 1200 cincluding a first camera unit 1202 c and a second camera unit 1204 c,according to some embodiments. In particular, FIG. 12C illustratesexample magnet arrangements of the first camera unit 1202 c and thesecond camera unit 1204 c. The first camera unit 1202 c and the secondcamera unit 1204 c may include coils (e.g., the example coilarrangements illustrated in FIG. 12B) configured to magneticallyinteract with magnets of the example magnet arrangements.

The first camera unit 1202 c may include a first VCM actuator configuredto move a first optical package 1206 c. For instance, the first VCMactuator may be configured to move the first optical package 1206 calong a first optical axis and/or along a first plane that is orthogonalto the first optical axis. The first optical package 1206 c may includeone or more lenses that define the first optical axis.

In some embodiments, the first VCM actuator of the first camera unit1202 c may include a symmetric magnet arrangement. For example, thefirst camera unit may be rectangular in plan, and the symmetric magnetarrangement may include multiple magnets that are individually arrangedto exhibit mirror symmetry about a respective plane that is angled, at anon-zero angle, with respect to at least one side of the first cameraunit 1202 c. In some examples, the symmetric magnet arrangement mayinclude four magnets that are individually arranged to exhibit mirrorsymmetry about a respective plane that is angled, at a non-zero angle,with respect to at least one side of the first camera unit 1202 c. Forinstance, in some embodiments, the magnets may be individually arrangedto exhibit mirror symmetry about a respective plane that is angled at orabout 45 degrees with respect to at least one side of the first cameraunit 1202 c.

In some examples, the first VCM actuator may include a first magnet 1208c, a second magnet 1210 c, a third magnet 1212 c, and a fourth magnet1214 c.

For instance, in some embodiments, the magnets 1208 c-1214 c may beindividually arranged to exhibit mirror symmetry about a respectiveplane that is angled at or about 45 degrees with respect to at least oneside of the first camera unit 1202 c.

As illustrated in FIG. 12C, the magnets 1208 c-1214 c may be cornermagnets. That is, the magnets 1208 c-1214 c may be individually disposedproximate a respective corner of the first camera unit 1202 c. Forexample, the first magnet 1208 c may be disposed proximate a firstcorner 1216 c of the first camera unit 1202 c, the second magnet 1210 cmay be disposed proximate a second corner 1218 c of the first cameraunit 1202 c, the third magnet 1212 c may be disposed proximate a thirdcorner 1220 c of the first camera unit 1202 c, and/or the fourth magnet1214 c may be disposed proximate a fourth corner 1222 c of the firstcamera unit 1202 c.

In some embodiments, the first magnet 1208 c, the second magnet 1210 c,the third magnet 1212 c, and/or the fourth magnet 1214 c may each be asingle pole magnet. In other embodiments, the first magnet 1208 c, thesecond magnet 1210 c, the third magnet 1212 c, and/or the fourth magnet1214 c may each be a dual pole magnet. The arrows depicted in FIG. 12Cindicate example polarity directions of the magnets.

The second camera unit 1204 c may include a second VCM actuatorconfigured to move a second optical package 1224 c. For instance, thesecond VCM actuator may be configured to move the second optical package1224 c along a second optical axis and/or along a second plane that isorthogonal to the second optical axis. The second optical package 1224 cmay include one or more lenses that define the second optical axis.

In some embodiments, the second VCM actuator of the second camera unit1204 c may include an asymmetric magnet arrangement. For example, thesecond camera unit 1204 c may be rectangular in plan, and the asymmetricmagnet arrangement may include a first magnet 1226 c (e.g., an actuatorlateral magnet) disposed proximate a first side 1228 c of the secondcamera unit 1204 c, a second magnet 1230 c (e.g., an actuator transversemagnet) disposed proximate a second side 1232 c of the second cameraunit 1204 a, and a third magnet 1234 c (e.g., an actuator transversemagnet) disposed proximate a third side 1236 c of the second camera unit1204 c. The third side 1236 c of the second camera unit 1204 c may beopposite the second side 1232 c of the second camera unit 1204 c.

In some embodiments, no magnets are disposed proximate a fourth side1238 c of the second camera unit 1204 c. The fourth side 1238 c of thesecond camera unit 1204 c may be opposite the first side 1228 c of thesecond camera unit 1204 c. In various examples, a dummy mass 1240 c maybe disposed proximate the fourth side 1238 c of the second camera unit1204 c. The dummy mass 1240 c may be configured to act as acounterbalance to the first magnet 1226 c disposed proximate the firstside 1228 c of the second camera unit 1204 c.

In some embodiments, the first magnet 1226 c may be a single polemagnet. Furthermore, the second magnet 1230 c and the third magnet 1234c may each be a dual pole magnet. The arrows depicted in FIG. 12Cindicate example polarity directions of the magnets. It should beunderstood, however, that the magnets may have polarity directions thatare different than those illustrated in FIG. 12C. Furthermore, in otherembodiments, the first magnet 1226 c may be a dual pole magnet, thesecond magnet 1230 c may be a single pole magnet, and/or the thirdmagnet 1234 c may be a single pole magnet.

In some embodiments, the first camera unit 1202 c may be disposedadjacent to the second camera unit 1204 c. For example, the first cameraunit 1202 c and the second camera unit 1204 c may each be rectangular inplan, and the first camera unit 1202 c may be disposed adjacent to thesecond camera unit 1204 c along a first axis 1242 c that intersects asecond axis 1244 c. For instance, the second axis 1244 c may extendthrough the first optical package 1206 c of the first camera unit 1202 cand the second optical package 1224 c of the second camera unit 1204 c.In some instances, the second axis 1244 c may be substantiallyperpendicular to the first axis 1242 c. The first side 1228 c of thesecond camera unit 1228 c may be distal to the first axis 1242 c.Furthermore, the first magnet 1226 c may have a longitudinal axis thatis substantially parallel to the first axis 1242 c. The fourth side 1238c may be proximal to the first axis 1242 c. Furthermore, dummy mass 1240c may have a longitudinal axis that is substantially parallel to thefirst axis 1242 c.

In some non-limiting examples, the first camera unit 1202 c and thesecond camera unit 1204 c may be configured such that magneticinteraction between the first camera unit 1202 c and the second cameraunit 1204 c is mitigated. The first VCM actuator of the first cameraunit 1202 c may include one or more magnets that are disposed proximatethe second VCM actuator of the second camera unit 1204 c. For instance,in some embodiments, the second magnet 1210 c and the third magnet 1212c of the second VCM actuator of the first camera unit 1202 c may bedisposed proximate the second camera unit 1204 c, and thus may beconsidered as a first set of near magnets relative to the second cameraunit 1204 c. Similarly, the second VCM actuator of the second cameraunit 1204 c may include one or more magnets that are disposed proximatethe first VCM actuator of the first camera unit 1202 c. For instance,the second magnet 1230 c and the third magnet 1234 c of the second VCMactuator of the second camera unit 1204 c may be disposed proximate thefirst camera unit 1202 c, and thus may be considered as a second set ofnear magnets relative to the first camera unit 1202 c.

In various embodiments, each magnet of the first set of near magnets ofthe first camera unit 1202 c may be a single pole magnet, and eachmagnet of the second set of near magnets of the second camera unit 1204c may be a dual pole magnet. In some cases, such a configuration maymitigate magnetic interaction between the first camera unit 1202 c andthe second camera unit 1204 c. That is, by configuring the first cameraunit 1202 c and the second camera unit 1204 c such that single polemagnets of the first camera unit 1202 c and dual pole magnets of thesecond camera unit 1204 c are nearest each other, the magneticinteraction between the camera units 1202 c and 1204 c may be mitigatedrelative to some other configurations (e.g, the example magnetarrangement 1300 a illustrated in FIG. 13A). The mitigated magneticinteraction may be due to the particular shapes and extensions of themagnetic fields of the single pole magnets and the dual pole magnets, asdiscussed in further detail below with reference to FIGS. 13A and 13B.

FIG. 13A depicts an example magnet arrangement that includes a firstsingle pole magnet adjacent to a second single pole magnet. FIG. 13Bdepicts an example magnet arrangement that includes a single pole magnetadjacent to a dual pole magnet. FIGS. 13A and 13B illustrate adifference in amount of magnetic interaction between the singlepole-single pole magnet arrangement of FIG. 13A and the single pole-dualpole magnet arrangement of FIG. 13B. In some examples, the singlepole-dual pole magnet arrangement of FIG. 13B is illustrative ofmitigated magnetic interaction between the first camera unit 1202 c andthe second camera unit 1204 c described above with reference to FIG.12C.

As illustrated in FIG. 13A, the example magnet arrangement 1300 aincludes a first single pole magnet 1302 a and a second single polemagnet 1304 a. The first single pole magnet 1302 a is adjacent to thesecond single pole magnet 1304 a. The first single pole magnet 1302 amay have a first magnetic field 1306 a. The second single pole magnet1304 a may have a second magnetic field 1308 a. The first magnetic field1306 a may extend away from the first single pole magnet 1302 a, and thesecond magnetic field 1308 a may extend away from the second single polemagnet 1304 a. For example, the first magnetic field 1306 a of the firstsingle pole magnet 1306 a may extend toward the second single polemagnet 1304 a and the second magnetic field 1308 a may extend toward thefirst single pole magnet 1302 a such that the first magnetic field 1306a and the second magnetic field 1308 a interact, as indicated by theoverlapping magnetic field lines within the dashed line rectangle 1310a.

As illustrated in FIG. 13B, the example magnet arrangement 1300 bincludes a single pole magnet 1302 b and a dual pole magnet 1304 b. Thesingle pole magnet 1302 b is adjacent to the dual pole magnet 1304 b.The single pole magnet 1302 b may have a first magnetic field 1306 b.The dual pole magnet 1304 b may have a second magnetic field 1308 b. Dueto the respective polarity configurations of the single pole magnet 1302b and the dual pole magnet 1304 b, the first magnetic field 1306 b mayextend away from the single pole magnet 1302 b to a greater extent thanthe second magnetic field 1308 b extends away from dual pole magnet 1304b. The tightness of the extension of the second magnetic field 1308 bwith respect to the dual pole magnet 1304 b may mitigate interactionbetween the second magnetic field 1308 b of the dual pole magnet 1304 band the first magnetic field 1306 b of the single pole magnet 1302 b,e.g., as indicated by the magnetic field lines not overlapping withinthe dashed line rectangle 1310 b. In some examples, the single pole-dualpole magnet arrangement of FIG. 13B is illustrative of mitigatedmagnetic interaction between the first camera unit 1202 c and the secondcamera unit 1204 c described above with reference to FIG. 12C.

Contact/motion module 1530 may detect contact with touch screen 1512 (inconjunction with display controller 1556) and other touch sensitivedevices (e.g., a touchpad or physical click wheel). Contact/motionmodule 1530 includes various software components for performing variousoperations related to detection of contact, such as determining ifcontact has occurred (e.g., detecting a finger-down event), determiningif there is movement of the contact and tracking the movement across thetouch-sensitive surface (e.g., detecting one or more finger-draggingevents), and determining if the contact has ceased (e.g., detecting afinger-up event or a break in contact). Contact/motion module 1530receives contact data from the touch-sensitive surface. Determiningmovement of the point of contact, which is represented by a series ofcontact data, may include determining speed (magnitude), velocity(magnitude and direction), and/or an acceleration (a change in magnitudeand/or direction) of the point of contact. These operations may beapplied to single contacts (e.g., one finger contacts) or to multiplesimultaneous contacts (e.g., “multitouch”/multiple finger contacts). Insome embodiments, contact/motion module 1530 and display controller 1556detect contact on a touchpad.

Contact/motion module 1530 may detect a gesture input by a user.Different gestures on the touch-sensitive surface have different contactpatterns.
